Second, I got another version of rpm from another site but this time it gavea different problem. This same problem persisted despite that I've uninstalled
(ie "rpm -e ... ") :

# rpm -i ./clamav-0.96.1-1.el4.rf.i386.rpm file /etc/freshclam.conf from install of clamav-0.96.1-1.el4.rf conflicts with file from package clamav-0.91.2-1.el4.rf file /usr/bin/clamscan from install of clamav-0.96.1-1.el4.rf conflicts with file from package clamav-0.91.2-1.el4.rf

When I repeated "rpm -i ./clamav-0.96.1-1.el4.rf.i386.rpm" above, it still gave
the same "conflicts" errors. I also tried renaming the above 8 conflictingfiles & reinstall but it still gave the same error
